Most Helpful Guy
Skinny people with body issues can ask if they look ok, but doing so in the presence of a fatty is somewhat insensitive. It's like the teenage girl freaking out over one pimple, when her friend beside her has massive acne problems all over her body.
The scenario you are illustrating is one where a person complains about an issue that is of small magnitude, within earshot of someone who is having the same issue, but at a huge magnitude. You are sure to get the scorn of others who are having the same problem, but to a much larger degree than you.
Today, this scenario goes far beyond "earshot". Bloggers and posters who complain about small problems online, will likely be swarmed with the millions of people who come across the blog who have bigger issues.
Bottom line is, don't complain online. You won't get any sympathy. Lots of trolls out there, and really, the opinion of faceless anonymous people are irrelevant.
